This is a front 4-Plus U-bolt Flip Kit from Man-a-Fre. As others have complained, the u-bolts are a little wide, but that really wasn't a big deal. The problem was the limited amount of clearance in which to work. Specifically, I could only turn the inner nuts about 15 degrees at time with a 24" ratchet. I couldn't get enough torque with a shorter ratchet and had to use a deep socket because of the thread length. When I do the other side I think I'll cut the excess thread off the u-bolts after the nuts are snugged up. A shallow socket will give me a little more room to work. It's a nice product but what a pain.
